The risk of an enhanced level of radionuclides of the uranium and thorium decay series in the environment for reference plant species (Pinus sylvestris and Vicia cracca) was assessed. 238U, 230Th, 226Ra, 210Po, 232Th and 228Th concentration factors for plants were found to be lower than one. The aboveground parts of Vicia cracca sampled from the area of the radium production waste storage mainly accumulated 22Ra, Pinus sylvestris branches--210Pb, 226Ra and 210Po. LOEDR calculated for the chromosome aberration frequency in both plant studies was 17-71 microGy/h. LOERD values for the reproductive capacity decrease in P. sylvestris and V. cracca were 17-71 microGy/h and 116-258 microGy/h, correspondingly. EDR10 for the chromosome aberration frequency in P. sylvestris and V. cracca were 148 and 347 microGy/h, that is, correspondingly, 255 and 708 times higher that background values. EDR10 for the plant reproductive capacity was 11-34 microGy/h, which 19-69 times increases the background values.
评估了环境中铀和钍衰变系列放射性核素水平升高对参考植物物种（欧洲赤松和广布野豌豆）的风险。发现植物的238U、230Th、226Ra、210Po、232Th和228Th浓度因子低于1。从镭生产废料储存区采集的广布野豌豆地上部分主要积累22Ra，欧洲赤松树枝积累210Pb、226Ra和210Po。两项植物研究中针对染色体畸变频率计算的LOEDR为17 - 71微戈瑞/小时。欧洲赤松和广布野豌豆生殖能力下降的LOERD值分别为17 - 71微戈瑞/小时和116 - 258微戈瑞/小时。欧洲赤松和广布野豌豆染色体畸变频率的EDR10分别为148和347微戈瑞/小时，即分别比背景值高255和708倍。植物生殖能力的EDR10为11 - 34微戈瑞/小时，比背景值增加19 - 69倍。
